我正在阅读关于Android的房间库.我看到他们改变包装android来androidx.我不明白.请有人解释一下.

implementation "androidx.room:room-runtime:$room_version"
annotationProcessor "androidx.room:room-compiler:$room_version"

即使这也适用于android包装.

implementation "android.arch.persistence.room:runtime:$room_version"
annotationProcessor "android.arch.persistence.room:compiler:$room_version"

• 需要什么来包装新的支持库androidx而不是android.
• 用例和影响现有项目的因素.
